Yes you're looking in the wrong places!
We have a full chassis available for 68-70 B body, 70-74 E-body.
They are the only one out there that "bolts in" to the car with minimal floorpan mods.. Unlike more universal chassis that require you to cut the whole floor out, build mounts, or weld it to the rockers.
Where have we been? Well the B-body chassis was introduced in 2009-2010 and the E-body in 2011.
